APPLICATION Transducers of P20H series are applied for the continuous conversion of one quantity: high voltage or high current signal, uni or bipolar signal into a standard d.c. current or d.c. voltage signals, or into a digital form available through the RS-interface. The transducer is configurable through the PD14 programmer. With the aid of the programmer and the LPCon program, one can reprogram following parameters: - measurement averaging time, - conversion characteristic, - preservation of the output signal at overflows, - narrowing of the output signal, - RS485 transmission parameters, The transducer has a galvanic separation between individual blocks: - supply - measuring inputs - outputs and PD14 programmer 2. TRANSDUCER SET The transducer set is composed of: - P20H transducer............................................. 1 pc - user’s manual.................................................. 1 pc - guarantee card............................................... 1 pc - protection plug of the programmer socket..... 1 pc When unpacking the transducer, please check whether the type and execution code on the data plate correspond to the order. 3. BASIC REQUIREMENTS, OPERATIONAL SAFETY In the safety service scope, the transducer meets the requirements of the EN 61010-1 standard. Observations concerning the operational safety: · All operations concerning transport, installation, and commissioning as well as maintenance, must be carried out by qualified, skilled personnel, and national regulations for the prevention of accidents must be observed. · The programming of P20H transducer parameters must be carried out after disconnecting measuring circuits. · Before switching the transducer on, one must check the correctness of connections to the network. · Do not connect the transducer to the network through an autotransformer. · Before removing the transducer housing, one must switch the supply off and disconnect measuring circuits. The removal of the transducer housing during the guarantee contract period may cause its cancellation. · The transducer is destined to be installed and used in electromagnetic industrial environment conditions. · When connecting the supply, one must remember that a switch or a circuit-breaker should be installed in the building. This switch should be located near the device, easy accessible by the operator, and suitably marked as an element switching the meter off. · Non-authorized removal of the housing, inappropriate use, incorrect installation or operation, create the risk of injury to personnel or transducer damage. For more detailed information, please study the User’s Manual. 4. INSTALLATION 4.1. Fixing Way P20H transducers are destined to be fixed on a 35 mm rail acc. to EN 60715 standard. Overall dimensions and the fixing way are presented on the fig. 1. Fig. 1. Overall dimensions and fixing way of the P20H transducer 4.2. External Connection Diagrams The transducer has a separable strip with screw terminals, which enable the connection of supply and output by 2.5 mm2 cross-section external wires. The connection of input signals must be carried out to inseparable screw terminals with wires of maximal 1.5 mm2 crosssection. Fig. 2. Electrical connections of P20H transducer inputs. a) voltage b) current Fig. 3. Electrical connections of the P20U transducer supply and output: a) with analog output, b) with RS-485 interface 5. SERVICE After switching the transducer on, the work state diode should light in red for a moment, next it should light in green. Diode of the transducer work state: - the state diode lights in green – normal work, - the state diode lights in red – improper work parameters; one must configure the transducer again, - the state diode pulsates in red – lack of calibration or the non-volatile memory is damaged; one must return the transducer to the manufacturer. Diodes only in the option with RS-485 interface: - the RxD diode lights – reception of data, - the TxD diode lights – transmission of data. Fig. 4. View of the P20H transducer The write confirmation in registers is signaled by a short extinction of the state diode. Till the time to obtain the required number of correct measurements (acc. to the table 1), the arithmetical mean value of measurements which have been doing so far, is converted. The measurement of values beyond the measuring range causes the overflow setting and begins the counting of correct measurements from the beginning. The measurement is carried out on the mowing window principle. The time is set up on 1 s by the manufacturer. When the averaging time is less than 10 sec – the single measurement lasts ca 30 ms however, above 10 sec, the measurement lasts ca 0.5 sec. Table 1 Averaging time Number of averaged measurements 0.2s 0.4s 0.6s 0.8s 6 13 20 27 1s 34 3s 5s 103 172 10s 15s 20s 20 40 30 In the transducer , one can program the behaviour of the analog output (the recording of the output value in the option with RS-485) at overflows of the set up input measuring range. Set up values: expected on the output at lower overflow (Out-d) for a value below the lower input overflow (In-d) and the expected value on the output at upper overflow (Out-u) for values above the upper input overflow (In-u) – Values are presented in the table 3. 5.1. Transducer Configuration by Means of the LPCon Program The free delivered LPCon program, available in our www.lumel.com.pl page, is destined for the P20H transducer configuration. The detailed description of parameter configuration is presented in a separate user’s manual for programming (instruction for transducer configuration by means of the LPCon program). In the option with RS-485 interface, the transducer can be configured directly through the interface. When configuring the transducer through the PD14 programmer, one must turn the RS-485 interface off. 5.2.
